briidea Bluetooth RV Freshwater Tank Level Monitor with App & LED Display — Auto-Sense, Precise Detection, 7-32V DC for RVs, Boats & Caravans

Upgraded Bluetooth-enabled freshwater tank monitor from briidea that sends real-time level updates to your phone via the companion app. Ideal for RV trips, boats, caravans or household tanks, it helps you avoid unexpected water shortages. The LED indicator panel includes a smart proximity sensor that automatically lights when you come within 1.3 feet and switches off as you walk away, plus selectable always-on or always-off modes for flexible use. Built with advanced sensing technology and a professional hydrophobic coating, the unit prevents false readings from water vapor to deliver consistently accurate measurements. A built-in memory retains your calibration settings so no recalibration is required after power outages. Designed for plastic tanks where length is twice the width (accuracy may be affected on metal tanks) and accepts a wide 7-32V DC input, making it well suited for off-grid RVs, boats, caravans and other freshwater tank monitoring needs.
